How the Comparezi Score works

In short

Each category has a published set of weights. For every weighted specification, a product's value is placed between the lowest and highest value in its category (0 to 100 %), multiplied by the weight, and the results are summed to a score from 0 to 100. Specifications a brand does not publish are left out, and the score is taken over the specifications that are published; the page shows which ones were left out. A product with less than 70 % of the weight published gets no score rather than one built on gaps. Head-to-head verdicts such as "better for gaming" are only stated when both products publish every specification behind them. The score is a computed figure, not a rating: it never uses reviews, prices or commissions.

What changes the score

  • A new version of a category's weights. Old versions stay listed below with their dates.
  • New products in the category: they can move the lowest or highest value, which moves everyone's position.
  • Corrected specifications (see the corrections policy).

Capacity (tons) is not scored: pick the size for your room, then compare scores within it.
